Abstract：
In recent years, research investigating the dose-response to sprint interval training (SIT) has provided evidence that the number and duration of repetitions in a SIT session can be reduced whilst preserving the beneficial health-related adaptations. Together this research has led to the development of protocols involving minimal doses of SIT: regularly performing just two or three 20-30 s all-out sprints in a 10 min training session has been shown to elicit beneficial metabolic and cardiovascular adaptations. These SIT protocols, which we originally termed \"reduced-exertion high-intensity interval training\" (or REHIT), have the potential to remove many of the common barriers associated with other SIT protocols, as well as with HIT and aerobic exercise. Here, we critically review the evidence on the efficacy, feasibility and acceptability, and effectiveness of REHIT for improving health and fitness.
摘要：
近年来,调查冲刺间隔训练（SIT）的剂量反应的研究提供了证据，表明可以减少SIT会话中重复的次数和持续时间，同时保留与健康相关的有益适应性。这项研究共同导致了涉及最小剂量SIT的方案的开发：在10分钟的训练中定期进行两到三个20-30秒的全部冲刺已被证明可以引起有益的代谢和心血管适应。这些SIT协议，我们最初称之为“减少劳累命中”(或重复)，有可能消除与其他SIT协议相关的许多常见障碍，以及HIT和有氧运动。这里,我们批判性地回顾了关于疗效的证据，可行性和可接受性，以及REHIT对改善健康和健身的有效性。
